emacs-app @29.4-imagemagick+nativecomp+rsvg+treesitter-xwidgets: Dependency cycle

[mcookly (Maximilian Cook)]

When installing emacs-app with a new MacPorts installation, the process fails when MacPorts tries to install librsvg, vala and graphviz:

Error: The following dependencies were not installed because all of them have unmet dependencies (likely due to a dependency cycle): librsvg vala graphviz
Error: Follow https://guide.macports.org/#project.tickets if you believe there
is a bug.
Error: Processing of port emacs-app failed

I have not run into this issue when trying to install emacs-app@29.4 without rsvg.

Anyhow it's easy to bypass by installing graphviz first, but I wanted to flag the issue.
